Non-infectious disease - Homeostasis

Question 1

Homeostasis

Answer 1

Homeostasis is the maintenance by an organism of a relatively constant internal state (a state of balance), to allow them to function at their optimal metabolic efficiency regardless of external changes in the environment.

Question 2

THE NEGATIVE FEEDBACK SYSTEM

Answer 2

The process by which this occurs is the stimulus-response pathway. A body system in which a response is intiiated to counteract a stimulus (anything that induces a response) and reutrn internal conditons to setpoint, maintaining hometostasis.

Question 3

thermoregulation

Answer 3

The regulation of body temperature and ability to maintain an organism’s internal body temperature is coordinated by the nervous system.

Question 4

Blood glucose

Answer 4

Glucose is essential for the production of ATP during cellular respiration. Maintenance of glucose levels are coordinated by the endocrine system.

Question 5

Osmoregulation

Answer 5

Involves the maintenance of osmotic pressure (water and salt balance).

Question 6

Hypothalamus

Answer 6

The hypothamlus (region in the lower central part of brain) is an important control centre in a negative feedback system.

Question 7

behavioural, structural and physiological adaptations

Answer 7

BEHAVIOURAL - The way an organism acts.

PHYSIOLOGICAL - The way the organisms body functions

STRUCTURAL - The physical characteristics of the organism
